  The formula presented, $\huge \color{DeepSkyBlue} |\Phi^+\rangle = \frac{1}{\sqrt{2}}(|00\rangle + |11\rangle)$, describes one of the most well-known entangled states, called a **Bell state** or **maximally entangled state**. This state is fundamental in quantum computing theory and quantum cryptography, as in the case of Artur Ekert's protocol.
 
+ - **$\huge |\Phi^+\rangle$**: Represents the quantum state vector in Dirac notation (also known as bra-ket notation). The state $|\Phi^+\rangle$ is one of the four Bell states, which are entangled qubit states.
